CLOTH-GUIDING MECHANISM FOR CLOTH-FINISHING MACHINES.

SPECIFICATION forming part of Letters Patent No. 463,581, dated November17, 1891.

' Application filed June 11 1890. Serial No. 355,083- (No model.

To all whom it may concern.-

Be it known that I, WILLIAM 0.1EIROE, a citizen of the United States,residing at Providence, in the State of Rhode Island, have invented anew and useful Improvement in Cloth-Guiding Mechanism forCloth-Finishing Machines, of which the following is a specification.

In feedingwebs of-clothto cloth-finishin g 111 achines it is desirableto provide an automatic feeding device which is efficient in itsoperation and notliable to get out of order; and to this end myinventionconsists in the employment of a screw and nut for producing the guidingmovement of the guide-rollers of the -machine, as hereinafter fully setforth.

Figure 1 represents a top view of my improved cloth-guiding mechanism ormachine with the pivoted guide-ro1l broken away and the detectorguide-plate removed. Fig. 2 represents an elevation at the outer side ofthe machine. Fig. 3 represents a side view of the screw, which is madein the form of a sliding sleeve. Fig. i represents a vertical sectiontaken in the line a: w of Fig. 1'. Fig. 5 represents a vertical sectiontaken in the line y y of Fig. 1, showing the guiding-plate in position.Fig. 6 represents 'avertical section 'taken in the line .2 a of Fig. 1through the 0- aXis of the direct-acting guide-roller. Fig. 7

represents a top View of the detector guideplateseparate from themachine. Fig. 8 represents a vertical section taken in the line to 'w ofFig. 5 through the screw-sleeve. Fig. 9 5 represents atop view of themachine, showing a modification in Which the nut is made to slideinstead of the screw, the guide-plate being removed to show the screwand nuts. Fig. 10 represents a vertical section taken in the line 00 wof Fig. 9.

In the accompanying drawings, Figs. 1 and 2, A represents the frame ofthe machine.

B is the driving-shaft, upon which is placed the pulley C, and upon theshaft B is also placed the sliding sleeve E, which is held to rotatewith the shaft B by means of the groove a, made in the shaft, and thepin 12,

which passes from the sleeve E into the groove a.

Upon the shaft B and loosely embracing the sleeve E is placed the yokeF, which is pro- E is provided with a right-hand spiral groove videdwith a rack c, and the forward end of the yoke F is supported in aproper sliding position by means of the guide-rod G, which passesthrough suitable perforations made in 5 5 the arms (I (Z of the yoke Fand is held in the perforated standard 0 of the frame. The slidingsleeve E and yoke F will thus be adapted for a limited movement alongthe shaft B between the bearing-standardsN N. The rack c engages withthe teeth of the gear H, which is either connected with or forms a partof the pivoted head I, which carries the guide-roller J, (shown by thebroken lines in Fig. 1,) the said guide-roller being thus caused tochange its angular position to guide the edge of the web upon themovement of the sliding sleeve E in either direction upon the shaft'B.The periphery of the sliding sleeve g and a left-hand spiral groove g,and upon the sleeve E, between the fixed standards h h, are placed thenuts K K, the nut K being provided with a spiral thread i, which fitsthe right-hand spiral groove g of the sleeve, and the nut K is providedwith a similar spiral thread 1', which fits the lefthand spiral grooveg, and between the nuts K K is placed the loose ring or washer j. Thenuts K K are adapted to revolve with the sleeve E and are provided withthe teeth m, which are adapted to engage with the projecting lower endsof the detectors L L. The detector L is pivoted to the fixed stud n andis provided with a hook 0, which is adapted 85 to engage with the teethm of the nut K, and the detector L is also pivoted to the stud n andprovided with an arm 0, which is adapted to engage with the teeth m ofthe nut K. The detector L is over-balanced upon the pivot-stud a, sothat the hook 0 will be out of engagement with the teeth of the nut Kuntil the engaging upper end 19 is carried forward by engagement withthe Web, and the companion detector Lis overbalanced, so that the 5 arm0 will be in engagement with the teeth of the nut K until the engagingupper end 13 is also carried forward by the web. To'the stud n isattached the detector guide-plate M, which is provided with the slot q,adapted to [00 receive the projecting upper ends of the detectors L L.

To the projecting arm r of the standard N is attached the stud 3, uponwhich is loosely placed the guide-roller O, which is provided with anannular groove 2, the said groove be ing adapted to receive the fork P,which is attached to the yoke F, so that whenever the said sleeve andyoke are moved in either direction a corresponding movement will beimparted to the guide-roller 0. Upon the stand ard N is also placed thefixed roller Q and the fiat supplementary guide R.

Vhen the edge of the web is running through the machine in the line asas, Fig. 1, in engagement with the upper end 1) of the detector L, thearm 0 will be thrown by the friction of the web out of engagement withthe teeth of the nut K, so that both of the nuts K and K will revolvewith the sleeve E, which will thus rest in a fixed position upon theshaft 13, and if the edgeof the web should then run outwardly onto theend 19 of the de tector L this would cause the hook end 0 of thedetector to'engagc with the teeth m of the nut K, thus stopping therevolution of the same and causing the endwise movement of the sleeveand lateral movement of the yoke, which will cause an angular movementof the guide-roller J and a direct axial movement of the guide-roller Oto carry the edge of the web back to the true line, and when the edge ofthe web runs inwardly and off from the end 19 of the detector L the arm0' will drop into engagement with the teeth on of the nut K, thusstopping the rotation of the same with the sleeve and causing theendwise movement of the sleeve upon the shaft B and the correspondingangular movement of the guide-roller J and direct movement of theguide-roller O to carry the edge of the web again back to the trueline.

A modification of my invention is shown in Figs. 9 and 10, in which thesleeve or double screw is either made stationary upon or integral withthe shaft, and the nuts are adapted for a sliding movement upon theengagement of the detectors therewith, the yoke F being made to embracethe nuts upon the screw, so as to move therewith, the operation of themachine remaining as before, and in this case the nuts K K are madeelongated in order that the lateral movement of the same will notinterfere with the proper action of the detectors.

The operating'screw can be driven either by means of a driving-belt uponthe pulley G (shown in Fig. 1) or by means of the forward movement ofthe web over the roller 0, (shown in Figs, 9 and 10,) and either one orboth of the guide-rollers can be employed.

If the machine when driven by a belt upon the pulley G is allowed to runwithout being threaded with a web, there will be danger of damage to themachine by the continued engagement of the detector L with the teeth ofthe nut K, thus causing the unregulated continued movement of the yoke Funtil such movement is obstructed by injurious engagement, and in orderto guard against such a result a guide-arm or cam r is arranged upon theyoke 1 as shown in Figs. t and 5,to raise the catch-arm 0 out ofengagement with the nut K before the dangerous extreme of move ment hasbeen reached.

I make no broad claim to the combination, with a guide-roller adapted toguide the movement of the edge of the Web,-a roller-support which isadapted to change the direction of the axis of the guide-roller, andreversing devices in operative connection with the said roller-support,of driving means for actuating the reversing devices, and a bearing forthe driving means from which as a resistingbase the power is applied tothe reversing devices, the said bearing being independent of the angularmovement of the roller-sup port; neither do I make a broad claim to thecombination, with a guide-roller adapted to guide the movement of theedge of the web, a roller-support which is adapted for'angular movementto change the direction of the axis of the guide-roller, and reversingdevices in operative connection with the said roller-support, of adriving means for actuating the reversing devices, a bearing for thedriving means from which as a resistingbase the power is applied tothereversing devices, thesaid bearing being independent of the angularmovement of the roller-support, and a detector which engages with thereversing devices upon a variation in the running edge of the web, asthe same was not my invention.

I claim as my invention 1. The combination, witlr a direct-movingguide-roller adapted to carry the edge of the web to the true line, of arotaryscrew-in operative connection with the guide-roller, a nut adaptedto rotate with the screw, and a detector adapted for engagement with therunning edge of the web and with the nut to stop its rotation and causethe required direct movement of the web by the direct movement of theguide-roller, substantially as described. v

2. The combination, with a pivoted guideroller adapted to guide. the.edge of the web to the true line, of a rotary screw in operativeconnection with the guide-roller,a not adapted to rotate with the screw,and a detector adapted for engagement with the running edge of the weband with thenut to stop its rotation and cause the required guidingmovement of the pivoted guide-roller, sub* stantially as described.

The combination, with a guide-roller adapted to cause the lateralmovement of the edge of the web, of a i'everselythreaded r0 .tary screwin operative connection with the guide-roller, a right-hand nut and aleft-hand not adapted to rotate with the screw, and the detectorsadapted toengage with the nuts to stop their rotation and cause therequired movement of the guide-ro1lcr, substantially as described.

4. The combination, With a guide-roller adapted to cause the lateralmovement of the edge of the web, of a rotary screw in operativeconnection with the guide-roller, a nut adapted to rotate With thescrew, a detector adapted for engagement with the running edge of theweb and with the nut to stop its rotation and cause the requiredmovementof the guide-roller, and the guide-arm adapted to disengage thedetector to prevent a dan- 1o gerous excess of movement, substantiallyas described.
